ACL_CREATE_ENTRY(3)					   BSD Library Functions Manual 				       ACL_CREATE_ENTRY(3)

NAME
     acl_create_entry, acl_create_entry_np -- create a new ACL entry

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/types.h>
     #include <sys/acl.h>

     int
     acl_create_entry(acl_t *acl_p, acl_entry_t *entry_p);

     int
     acl_create_entry_np(acl_t *acl_p, acl_entry_t *entry_p, int entry_index);

DESCRIPTION
     The acl_create_entry() function is a POSIX.1e call that creates a new ACL entry in the ACL pointed to by acl_p.  The function will return in
     entry_p a descriptor for this ACL entry.

     The acl_create_entry_np() function is a non-portable extension which allows the caller to specify the position of the created entry within
     the ACL.  If entry_index is ACL_FIRST_ENTRY the entry will be created at the head of the ACL.  If entry_index is ACL_LAST_ENTRY the entry
     will be created at the end of the ACL.  After inserting an ACL entry with an entry_index other than ACL_LAST_ENTRY the behaviour of any
     acl_entry_t's previously obtained from the ACL by acl_create_entry() or acl_get_entry() is undefined.

RETURN VALUES
     The acl_create_entry() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to
     indicate the error.

ERRORS
     The acl_create_entry() and acl_create_entry_np() functions fail if:

     [EINVAL]		Argument acl_p does not point to a pointer to a valid ACL.

     [ENOMEM]		The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management con-
			straints.

     [ERANGE]		The entry_index argument to acl_create_entry_np() is greater than the number of entries in the ACL.

STANDARDS
     POSIX.1e is described in IEEE POSIX.1e draft 17.
